Checks whether the evaluation of an expression can throw an exception

Used within noexcept specifier when the fact if the function can throw depends on template parameters.

[edit] Syntax

noexcept( expression )

Returns an object of type ​bool​.

[edit] Explanation

The noexcept operator does not evaluate expression. The result is true if the expression contains at least one of the following potentially evaluated constructs:

• call to any type of function, which does not have non-throwing exception specification, unless it is a constant expression.
• throw expression
• dynamic_cast expression when the conversion needs a run time check
• typeid expression when argument type is polymorphic class type

On all other cases the result is false
